TURBINE.

To all whom it may concern:

'Be it known that I, JAMES BLAINE KIRBY, a citizen of the United States, residing at Seattle, in the county of King and State of WVashington, have invented certain new and useful Improvements in Steam or Water Turbine-Engines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a steam or water turbine engine, and has for its principal object the production of a rotary piston which is adapted to operate as steam or water is passed longitudinally along the same.

Another object of this invention is the production of a detachable nozzle which is carried adjacent the end-portion of the rotatable piston for supplying the same with steam or water.

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed. I

In the accompanying drawing :-Figure 1 is a side elevation of the engine. Fig. 2 is a central longitudinal section of the device showing the rotary piston in elevation. Fig. 3 is an enlarged section of one end-portion of the device illustrating the relative position of the nozzle and the rotary piston. Fig. 4 is a detail section showing a slightly modified form of head, which is adapted to limit the inward movement of the nozzle.

Referring to the accompanying drawing by numerals, 1 indicates the supporting blocks having integral bearings 2 formed upon their upper portions. These integral bearings 2 are provided with central openings 3, through which pass the end-portions of the rotary piston 4. This piston 4 is elongated and comprises a round body having a central bore 5 formed in one end for admission of the motor power. This bore 5 extends for a spaced distance into the piston 4 and then passes to the outer side so as to form a continuous groove 6 upon the outer periphery of the piston. A casing 7 is carried upon the outer portion of the piston 4 so as to incase the groove 6 and prevent the escaping of water or steam as the same passes through the groove 6. After the steam passes through this groove it will be discharged through an exhaust opening, as disclosed in dotted lines at 8. By referring to Figs. 2 and 4 it will be seen that the bear- Specification of Letters Patent.

ings 3 are each provided with a beveled face 9 ad acent the opening 3 into which the tapered end 10 of the casing 7 is adapted to -fit for preventing any longitudinal movement of the casing 7 upon the piston. In order to prevent the piston-4 from having longitudinal movement within the bearings 2 there is provided, adjacent each end of the piston, a washer 11 which is held in engagement with the piston by means of the setscrews 12. These washers bear against the outer faces of the bearings 2 and in this manner hold the rotary piston in a correct position within the openings 3. In order to supply this rotary piston with steam or water for rotating the same, there is provided an integral collar 13 upon one end of this piston. A retaining collar 14, having an overhanging internally-threaded portion 15 is positioned upon the rotary piston so as to allow the portion 15 to overhang the end of the rotary piston. A head 16 having internal threads 17 and a reduced threaded neck 18 is threaded into engagement with the retaining collar 14 and this head 16 is adapted to receive the collar nozzle 19 having an enlarged opening 20 formed in its inner end. The outer end of this nozzle 19 is provided with a reduced body 21 for the reception of the feed pipe 22. It will be noted by carefully referring to Fig. 4 that the nozzle is held at a spaced distance from the end of the bore 5 so as to form a steam chest 23.

lVhen this device is in use it will be seen that the steam or water will be supplied through the pipe 22 to the nozzle 19. It will then pass through the opening 20 and will be retained within the chest 23 wherefrom it will pass through the bore 5 through groove 6 and then through the exhaust opening 8. As the same is passed through the groove 6 it will be seen that the rotary piston 4 will be rotated according to the force with which the steam or water is passed into the same, thereby rotating a pulley 24 carried upon one end of the rotary piston. It will, of course, be obvious that a packing ring 25 may be placed between the collar 13 and the retaining collar 14 for preventing the escape of steam or water therebetween.

By referring to Fig. 4 it will be seen that the retaining collar 14 is threaded into engagement with the neck 26 of a slightly modified form of head 27. This head 27 is threaded internally as shown at 28 and is provided with an integral flange 29 upon its inner portion adjacent the inner end of the threaded portion 28 and this flange 29 is provided with an enlarged central opening 30 for allowing the steam to be passed therethrough. It will be seen that when the nozzle 31 is threaded into the head 27 it will engage the flange 29 whereby the inward movement of the same will be limited and thus always allowing a space between the flange 29 and the end of the rotary piston l for forming a chest 32. In other respects this form, as disclosed in Fig. 4-, is similar to the preferred form disclosed in Figs. 2 and From the foregoing description it will be seen that a simple device has been produced which is formed so as to be operated by steam or water which may be easily supplied in one end-portion.

What I claim is:

1. An engine of the class described, comprising a plurality of SUPPOllllIlg blocks, said blocks provided upon their upper portions with hollow bearings, a rotary piston carried by said bearings, said piston provided upon its outer face with a longitudinally-extending groove, casing carried by said rotary piston for inclosing said groove, said bearings provided with inclined faces adjacent their inner portions, said casings provided with tapering ends engaging saic inclined faces for preventing said casing moving longitudinally upon said rotary piston, said piston also provided with longitudinally extending bores communicating with said groove, and means detachably secured to one end of said piston for supplying motive power to said groove.

2. An engine of the class described, comprising supporting bearings, a rotary piston carried by said bearings, said piston provided with a groove upon its outer face, means for inclosing said groove, said piston also provided with longitudinally-extending bores commin'iicating with said groove, a collar integrally formed upon one end of said piston, a retaining collar carried by said piston and overhanging said integral collar, a collar head threaded into engagement with said retaining collar, and a nozzle carried by said head for conducting steam or water into one of the bores formed in said piston whereby said piston may be rotated.

3. An engine of the class described comprising supporting bearings, a rotary piston positioned within said bearings, said piston provided with a longitudinallyextend ing groove upon its outer face, a casing inclosing said groove, said piston provided at one end with an integral collar, and a retaining collar carried by said piston and provided with an overhanging portion, a head having a reduced neck threaded into engagement with said retaining collar, a hollow nozzle detachably positioned within the interior of said head, said nozzle provided at its inner end with an enlarged opening formed in alinement with one of the bores formed in said piston, said nozzle positioned at a spaced distance from the end of said piston for forming a chest between the two, said nozzle adapted to conduct steam or water into said piston for operating the same.

4:. An engine of the class described comprising supporting bearings, a rotary piston carried by said bearings, said piston provided with longitudinallyextending bores in its end-portions and with a groove upon its outer face communicating with said bores, a casing carried by said piston for inolosing said groove, a retaining collar positioned upon one end of said piston, a head detachaloly carried by said retaining collar, said head provided with an internally-threaded portion, an internal flange integrally carried by said head, said nozzle adapted to engage said flange for limiting the inward movement of the same, the open ing formed in said flange adapted to be in alinement with one of said bores whereby water or steam may be passed into said piston for rotating the same.
